I have struts code like
<html:select property="ce">
<html:option value = "5">5</html:option>
<html:option value = "10">10</html:option>
<html:option value = "15">15</html:option>
</html:select>
<div id="dis">
<div>
if a option is selected,dojo should get the valu and multiply by 10 and display that in the div?how to do that.
Its sounds like you want something like this in the <body> tags:
<select dojoType="dijit.form.ComboBox" onChange="displayValue">
<option>5</option>
<option>10</option>
<option>15</option>
</select>
<div id="displayDiv"></div>
and something like this in the <script> tags:
dojo.require('dijit.form.ComboBox');
function displayValue(val) {
dojo.byId('displayDiv').innerHTML = (val * 10);
}
All assuming, of course, that you understand how to import the dojo.js source, and that your <body> tag has some dojo style applied to it (so that the comboBox dijit will render), like
<body class="tundra">
<script type ="text/javascript">function displayValue(combo){
dojo.byId("dis").innerHTML = combo.value * 10;
}</script>
<html:select property="ce" onchange="{displayValue(this);}">
<html:option value = "5">5</html:option>
<html:option value = "10">10</html:option>
<html:option value = "15">15</html:option>
</html:select>
<div id="dis">
<div>
